Place potatoes in a 9 by 13 greased pan. Season with salt and pepper.

Melt butter in a microwave. In a bowl add chopped onions, sour cream, cream of chicken soup and melted butter.

Pour soup mixture over potatoes and sprinkle with shredded cheddar cheese. Bake at 350 degrees for 45 minutes. Delicious! Make it look even more tasty by adding chopped parsley.
